| 摘 要： | 零价铁去除Cr(Ⅵ)的一系列批实验结果表明：水溶液中发生的氧化还原反应符合准一级反应；对于相同粒度的铁屑(比表面积2．89m^2／g)，固液比由05g／100mL增加到2．0g／100mL，Cr(Ⅵ)质量浓度达到排放标准所需反应时间从26．7min降为3．6min；在固液比相同、原水中Cr(Ⅵ)质量浓度不超过30mg／L时，原水质量浓度增大，达到饮用水标准的反应时间增加；其他条件相同，升高温度可提高零价铁与Cr(Ⅵ)的反应速率。

| Abstract: | The main goal of a series of laboratory experiments was to determine the efficiency of iron for removing hexavalent chromium. The results indicate that the reductive reaction of zero_valent iron with hexavalent chromium reaches the quasi_ first_order standard, that the ratio of the granular iron (BTE 2.89 m 2/g) to solution increases from 0.5 g/100 mL to 2.0 g/100 mL, and that the reaction time is reduced from 26.7 min to 3.6 min. It is also shown that the reaction time should be prolonged to meet the standard of drinking water because the concentration of initial solution within 30 mg/L increases when the quantity of iron is stable, and that the raising of the temperature promotes the removal of hexavalent chromium when other conditions are constant. |
